News Pro GK4 and Module Position menu1, menu2, menu3

Hi there,

I´m trying to change the Data Source of the GK4 Module in Menu Positions menu1,2,3 but nothing works.
I just want to display K2 Articles and tried everything ... no success. It always shows the default article from the quickstart-package with the dummy image.

the first time, i tried to save the new parameters ( K2 article with Id´s given), i got the error:
You are not permitted to use that link to directly access that page (#191)

Any suggestions?
THX
